Abstract
The friction performance of carbon/carbon composites is influenced by many factors.The current situation of internal and external studies for that are summarized,the influences of friction parameter,ambient and surface status on friction and wear behavior of carbon/carbon composites are evaluated.The factors including energy,rotational speed,pressure force,humidity,temperature,atmosphere,surface roughness and lubricating condition etc.are elaborated.Tribological behavior of C/C composites is the result influenced by serious factors.The excellent friction and wear properties can be displayed for appropriate friction parameter design,ambient factor and surface status under the certain material property.But the influence extent of each factor need be further studied.C/C composites are widely used in friction filed,but we should enlarge the dominance of friction,increase the friction stability and reduce wear loss,especially the oxidation wear loss at high temperature.
